REISNER MANUFACTURING COMPANY OF HAGERSTOWN, MARYLAND, A' CORPORATION OF MARYLAND Application filed April 18,

My invention relates broadly to valves for organs having means for accurately guiding and housing an armature member which forms the valve closure Within the valve structure whereby the armature is confined within a predetermined space.

Another object of my invention is to provide an organ valve construction having means to retain the armature thereof and prevent the armature blowing away when the plate containing the valve is removed from magnet base while under pressure of wind from the or an wind chest.

Still another 0 ject of my invention is to provide a construction of magnetic valve for organs wherein a disc type armature is provided having one surface area of magnetic material and an op osite surface area of fibrous material, the brous material being securely retained in position with respect to the magnetic material forming one side of the armature.

A further object of my invention is to provide a construction of magnetic valve for organs in which means are provided for guiding and housing a movable armature member within the valie structure for maintaining the armature in alignment with the actuating electro-magnets and eliminating substantial- 1 all noise due to valve movement heretoflire experienced in organ valves.

A still further object of my invention is to provide an assembly of magnetic valve for organs in which a minimum number of metallic parts may be secured together to form a housing for a movable armature member wherein means are provided for accurately centering and guiding the movable armature member with respect to the magnetic poles of the actuating electromagnets.

Other and further objects of my invention reside in the construction of the magnetic valve described in the specification hereinafter following and shown in the accompanying drawings in which:

My invention is directed to a construction of organ valve wherein the parts are extremely simple in their arrangements and assembly and in which substantially noiseless operation of the valve may be'obtained. I provide a cup structure which may be centered in a supporting plate forming part of the valve structure, which cupv structure is screw threaded to receive a valve seat against which the movable armature member is adapted to The armature member is confined in its movement to the space provided for such movement within the limits of the cup shaped retaining member which forms the housing for the armature. The armature is constituted by a circular plate of soft iron having an annular inturned edge which grips a tibrous sheet of material at the periphery thereof forming a padded face for one side of the armature which contacts with the adjustable valve seat forming an airtight closure.

Referring more particularly to the drawings, reference character 1 designates the electromagnet which may be of the horse-shoe type having poles 2 and 3 which enter recesses provided in the casting 4. The electromagnet carries electromagnet windings 5 which are included in the control circuit. The plate member 4 is provided with an interior air passage represented at (3 which terminates in a port 7 at one side of the plate 4 and in the air passage formed through the adjustable valve seat 8 at the other side of the plate 4. The plate 4 is provided with a depending plug member 9 grooved at 10 to receive the latch 11. The latch 11 is pivot-ally mounted at 12 on removable plate member 15 and is provided with an actuating lug member 14. The plate member 15 carries a gasket 16 thereon which provides a seal between the plate 15 and the side walls of the chamber onclosed by plate 4. The plate 15 is canted in assembling the valve structure and engaged beneath the projecting member 17 carried by depending member 18. By canting the p ate 15 and sliding it bacl: in position beneath the projection 17 at one end and telescoping the plate over the extending lug 9 and thereafter latching tlie member 11 in the groove 10 it is possible to secure the plate 1:) solidly in position with respect to the enclosure The plate 15 is apertured and provided with a downwardly depending apertured annular portion 19 which receives the cup shaped member 20. Various forms of the cup shaped member 20 are shown more clearly in perspective view in Figs. 7, 8 and 9 wherein the member consists of an annular plate 20 provided with upstanding dividing wall portions 20 each of which are segmental in contour and provide means for defining the path of movement of the armature member and permitting a free flow of air to exhaust when the magnet is energized and armature lifted from its seat, shown in Figs. 10 and 11. The armature member consists of a soft iron circular disc having a central portion 22 and an .innular inturned edge 23 which is rolled over the fibrous material 24 which covers one side of the valve. The fibrous side of the valve seats against the annular periphery of the adjustable valve seat 8. The valve seat 8 is cylindrical in form and is exteriorly screw threaded as designated at 25 to engage the interior screw threads 26 within the cup shaped member 20. By adjusting the valve seat 8, the movement oi the valve may be limited to the desired degree. The segmental wall member. 2 limit the movement of the valve laterally, while the longitudinal movement of the valve is controlled by the adjustment of the valve seat- 8, the valve cushioning against the fibrous member 27 which lines the recess 6 within the plate 4 immediately around the tips of the magnetic poles 2 and 3. The fibrous member 27 is cemented or glued into the base 4 and is retained therein by the wall portions 20 of the cup shaped member 20 which press upwardly against the member 21.

In Fig. 10 I have shown the plate 15 having a valve seat pressed directly thereupon as represented at 36 forming an annular peripheral seat at against which the valve disc rests. The guiding cup shaped memher is shown having its liat portion 20 surrounding the upstanding seat 35, with the wall portions 20" extending upwardly from the portion 20.

The plate member 4 is provided with a gas ket 28 which is arranged to seat against a hermetically sealed chamber with the port 7 connecting through the aperture 29 in the gasket 28. The gasket 28 is apertured at 30 around the olisets 32 and 33 in plate 4 and around the central portion 34 in plate 4.

It will be observed that the manufacture and assembly of the valve structure of my invention is extremely simple and that by virtue of the centering of the valve and the cushioning thereof the operation of the valve is substantially noiseless. The centering device may comprise diametrically opposed members, as illustrated in Fig. 7 or there may be three such members as shown in Fig. 8 or four independent outstanding segmental lugs may be provided as shown in Figure 9.

I have found the valve structure of my invention highly practical in its operation in securing silent valve control in organs where it is so important to prevent metallic clicks 0r noises from interfering with reproduced music.

While I have described my invention in certain of its preferred embodiments, I desire that it be understood that modifications may be made and that no limitations upon my invention are intended other than those imposed by the scope of the appended claims.
